GAS GENERATOR AND BURNER.

SPECIFICATION forming part of Letters Patent No. 410,944, datedSeptember 10, 1889.

Application filed April 11, 1889. Serial No. 306,775. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH G. STREET, a citizen of the United States,residing at Dallas, in the county of Dallas and State of Texas, haveinvented new and useful Improvements in Hydrocarbon Vapor Generators andBurners, of which the following is a specification.

This invention has for its object to improve the efficiency of that typeof vapor generators and burners wherein oil and air pipes enter a casinghaving burner-orifices and filled with a porous incombustible substance,which when heated vaporizes the oil.

The object of my invention I accomplish by the combination of deviceshereinafter described and claimed, reference being made to theaccompanying drawings, illustrating the invention, in which- Figure 1 isa vertical longitudinal section, and Fig. 2 a vertical transversesection, of my improved vapor generator and burner.

The referencenumeral 1 designates the body or casing of the vaporgenerator and burner. This casing may be composed of metal or anysuitable refractory material. Its form is preferably cylindrical, orapproximately so but it may be made in any desired shape. The ends ofthe casing 1 are closed by metallic heads 2, secured in place by anysuitable means. The casing-heads 2 are perforated at or about the centerto receive and support an oil-supply pipe 3, one end of which is closedby a screw-cap 4 on the outer side of the adjacent head. The other endof the oilpipe 3 connects with a vertical pipe 5, that leads from anoil-reservoir, and is provided with a valve 6, for regulating the supplyof oil delivered to the pipe 3, which pipe is provided with a series ofperforations 7, through which the oil is permitted to escape into apacking 8, of asbestus or similar incombustible material, with which thecasing 1 is filled. Each casing-head 2 is also perforated for passage ofa coiled air-supply pipe 9, the coiled portion of which extends throughthe casing from end to end adjacent to the walls thereof, the upperportions of the coils being provided with a number of j et-tubes 10,arranged in a plane above the oil-supply pipe 3, projecting upwardthrough the filling or packing 8 to a point above the same andregistering with a number of burner tips or nozzles 12 on the peripheryof the casing. The outer ends of the air-pipe 9 are preferably turneddownward, as shown, and are providedwith valves 13, opening inward, sothat air can be taken at either end of the coiled pipe.

The asbestus or other fire-proof packing material 8 is in a comminutedor disintegrated condition, so ,that while it is in suflicient quantityto compactly fill the casing around the oil-pipe 3 and coiled air-pipe 9it affords numerous capillary passages for the distribution of oilthroughout the packing.

The coiled air-supply pipe 9 furnishes an extended heating-surface forthe air that is delivered to the burner-nozzles 12, thereby facilitatinga rapid movement or feed of the air, and by means of the air-jet tubes10,1egistering with said burner nozzles or tips, a blow-pipe action isinduced that causes the vapor of the oil to be conveyed with agreatlyincreased evolution of heat. The oil that flows through theperforations 7 of the pipe 3 saturates the fire-proof packing material8, and under the action of heat a vapor is generated from the oil andescapes at the blowpipe burners 12, where it may be ignited.

This vapor-generator and blow-pipe burner maybe employed for variousheating purposes, the same as ordinary hydrocarbon-burners, andtherefore I do not deem it necessary to exhibit any particularapplication of the invention. The coiling of the air-pipe facilitatesthe heating of a comparatively large volume of air, so that such air isin proper heated condition at the critical moment of its union with thevaporized oil. The air-jet tubes being on the upper portions of thecoils and extending into the burner-tips on the upper side of thecasing, the heated air issuing from such air-jet tubes and burner-tipscreates a current which draws the vaporized oil through chambers for thepurpose of Warming buildings, for generating steam, and other pur poses;but this I do not broadly claim.

Having thus described my invention,what I claim is 1. A11 oil-vaporgenerator and burner, consisting of a casing containing a filling ofporous incombustible substance and provided at its upper portion with aplurality of burner-tips, an oil-supply pipe extending in the fillinglengthwise of the casing and having perforations, and an air-supply pipeextending through the filling and provided with a plurality of air-jettubes arranged in a plane above the oil-supply pipe, projecting upwardthrough the packing to a point above the same and registering with theburner-tips at the upper portion of the casing, for inducing the flow ofvaporized oil through the filling to the burner-tips and producingablow-pipe action, substantially as described.

2. A11 oil-vapor generator and burner, consisting of a casingeontaininga filling of porous inconibustible substance and provided at its upperportion with a plurality of burnertips, a perforated oil-supply pipeextending through the filling, and an air-supply pipe extending throughthe filling and opposite ends of the casing, having at its oppositeexternal ends the valves for the admission of air at either end of thepipe and provided with a plurality of air-jet tubes arranged in a planeabove the oil-supply pipe, projecting upward through the packing to apoint above the same and registering with the burnertips at the upperportion of the casing, substantially as and for the purposes described.

3. An oil-vapor generator and burner, consisting of a casing containinga filling of porous incombustible substance and provided at its upperportion with a plurality of burnertips, a perforated oil-supply pipeextendlng through the filling, and a coiled air-supply pipe located inand heated by the filling, and having portions of its coils providedwith a rjet tubes located in a plane above the 011- supply pipe,extending through the filling to a point above the same, and registeringwith the burner-tips at the upper portion of the casing, substantiallyas and for the purposes described.

at. An oil'vapor generator and burner, consisting of a casing containinga filling of porous ineombustible substance and provided at its upperportion with a plurality of burnertips, a perforated oil-supply pipeextending through the filling, and a coiled air-Suppl y pipe located inthe filling, extending through opposite ends of the casing, providedwith valves at its ends for receiving air at either end, and havingportions of its coils provided with air-jet tubes located in a planeabove the oil-supply pipe, extending through the filling, andregistering with the burner-tips at the upper portion of the casing,substantially as and for the purposes described.

In testimony whereof I have affixed my signature in presence of twowitnesses.
